Thanks so much.
Seems I'm also running into some licensing issues. For example, 2021 R2 seems to be fully licensed for the AM module but, curiously, the 2022 R2 version I get from my university disputes the validity of the AM licence. It's possisble that it's no longer licensed through that key but seems a little unlikely to me so I need to enquire with the university.
Regardless, your links are useful. I'll mark as answered.
